How old do dinosaurs live How old do dinosaurs really live?

The lifespan of a dinosaur.

The length of an animal's lifespan is often related to its growth pattern. Animals with unrestricted growth have a longer lifespan than animals with limited growth. If we apply the unrestricted growth patterns of living animals to the study of dinosaurs, the time required for some groups of dinosaurs to hatch from eggs to adulthood is as follows:

Protoceratosaurs took 26-38 years, medium-sized sauropods 82-118 years, and giant sauropods, such as Brachiosaurus, took more than 100 years. Then, if the dinosaur could live for the same length of time after growing into an adult, Brachiosaurus could also live for about 300 years.

Another factor that affects how fast or slow an animal grows is their metabolism. On average, hot-blooded vertebrates grow at least 10 times faster than cold-blooded animals. The faster it grows, the shorter the lifespan; The slower the growth, the longer the lifespan.

What kind of metabolism did dinosaurs have? Are they hot-blooded or cold-blooded? This is a key to our correct estimation of the lifespan of dinosaurs.

There is a lot of evidence that many dinosaur taxa were hot-blooded animals. If this is true, the lifespan of a dinosaur can be calculated using the growth patterns of living hot-blooded vertebrates. If it is a hot-blooded dinosaur, it can live for decades to more than 100 years.

In short, we don't know exactly how long dinosaurs lived for long ago. Some paleontologists, after studying the growth rings of some dinosaur bones, found that these dinosaurs were about 120 years old when they died.

Therefore, it is believed that dinosaurs may have lived longer, i.e. they may have lived to be 100-200 years old.

Most can be more than 100 years old, and a few are less than 100 years old.

Vegan dinosaurs lived comparatively longer.

For animals like dinosaurs, which lived hundreds of millions of years ago, the challenging question is: How long did they live? If you consult different popular science articles, you will get different answers.

In the case of giant sauropod dinosaurs, some believe that they lived only a few decades, but others believe that they lived to be hundreds of years old.

The method of estimating the lifespan of dinosaurs based on their size and metabolic rate is very crude and imprecise, because the comparison data of this method is that of living animals that are significantly different from dinosaurs. So, is there a more precise way to estimate the lifespan of a dinosaur?

Generally speaking, sauropods lived to be 40 to 60 years old, perhaps longer; Large theropod dinosaurs, like the famous Tyrannosaurus rex.

can live to be about 25 years old; Small theropod dinosaurs, like microraptors, lived only 3 to 10 years; Psittacosaurus, which is also a small dinosaur, could live longer than 10 years, perhaps reflecting the different levels of metabolism between ceratosaurs and small theropods. Large carnivorous dinosaurs lived for 20 to 50 years, and some species of dinosaurs lived for 100 200 years.

Some speculate that herbivorous dinosaurs lived longer than carnivorous dinosaurs, that large dinosaurs lived longer than small dinosaurs, that some small dinosaurs lived for decades at most, and that giant diplodocus.

Brontosaurus probably lived to be more than 200 years old. Brachiosaurus.

Maybe you can live for 300 years.

Is this the case? Biologists are also needed to continue their research and find answers as soon as possible.

Dinosaurs survived for hundreds of millions of years.

The dinosaur family is one of the longest-lived vertebrates. The earliest known fossilized dinosaur bones were found in Argentina, about 100 million years ago. The earliest known fossilized dinosaur footprints were found in some locations in Europe and South America, about 100 million years ago.

Traditionally, all dinosaurs became extinct at the end of the Cretaceous period, about 65 million years ago.

They were no longer found in the fossil record. According to this calculation, dinosaurs in the traditional sense spent about 100 million years on the earth. Since birds originated from dinosaurs and belong to a branch of the dinosaur family, dinosaurs in the modern sense include birds.

In this way, the dinosaur family has lived on the earth for about 100 million years.

The story of the dinosaurs

In the long era of dinosaurs, there were all kinds of dinosaurs. The dinosaur species of each era are different and have a strong imprint of the times. The Triassic was an early stage in the evolution of dinosaurs, with the emergence of major clades of dinosaurs including sauropods, theropods, and ornithischians, with the most famous representatives including Plateosaurus, which belonged to the protosauropods.

Ancient Brontosaurus belonging to the sauropods, Coelostosaurus belonging to theropods, and Pisanosaurus belonging to the ornithischian hips. The dinosaurs of this period were dominated by protosauropods and theropods, and less sauropods and ornithischians. Dinosaurs in the Triassic period were generally relatively small in size and mostly walked on two legs.

The earth has a history of 4.6 billion since its birth, and in such a long time, the earth has experienced a total of five mass extinctions, the last of which was the mass extinction of dinosaurs that occurred 65 million years ago.

Speaking of dinosaurs, I believe many people know that this is a huge creature that lived in the Cretaceous era 65 million years ago, and was the overlord of the earth at that time. The history of dinosaurs is very long, they have lived on the earth for about 100 million years, far surpassing most of the earth's creatures.

Some dinosaur bones have growth rings on them, but these fossils are relatively rare and cannot be fully analyzed. The longest-lived modern reptiles are turtles and turtles, which can live for hundreds of years. Some scientists believe that vegan dinosaurs with long necks may have lived longer than other dinosaurs.

If they are hot-blooded, they may live to be a hundred years old; If it is cold-blooded, it is possible to live to be two hundred years old or more. However, the lifespan of Tyrannosaurus rex is very short, with an average of only one year.

The lifespan of a dinosaur.

The length of an animal's lifespan is often related to its growth pattern. Non-restricted animals live longer than those of limited habitats. If we apply the unrestricted growth patterns of living animals to the study of dinosaurs, the time required for some groups of dinosaurs to hatch from eggs to adulthood is as follows:

Protoceratosaurus took 26-38 years, medium-sized ground sauropods 82-118 years, and giant sauropods, such as Brachiosaurus, took more than 100 years. Then, if a dinosaur grows into an adult and can live for the same long time, Brachiosaurus can also live for about 300 years.

Another factor that affects how fast or slow an animal grows is their metabolism. On average, hot-blooded vertebrates grow at least 10 times faster than cold-blooded animals. The faster it grows, the shorter the lifespan; The slower the growth, the longer the lifespan.

What kind of metabolism did dinosaurs have? Are they hot-blooded or cold-blooded? This is one of the keys to correctly estimating the lifespan of our dinosaurs.

There is a lot of evidence that many dinosaur taxa were hot-blooded animals. If this is true, the life span of the dinosaur can be calculated using the growth pattern of living hot-blooded vertebrates. If it is a hot-blooded dinosaur, the individual can live for decades to more than 100 years.

In short, we don't know exactly how long dinosaurs survived. Some paleontologists, after studying the growth rings of some dinosaurs, found that these dinosaurs died at about 120 years old.

Therefore, it is believed that dinosaurs may have lived longer, i.e. they may have lived to 100-200 years.
